We are familiar with the earlier futuristic airport proposals for London and here we have a new proposal for a floating airport in the middle of the Thames Estuary. Conceived by architecture firm Gensler, the proposed London Britannia Airport will include four five-kilometer floating runways.
In order to reduce the environmental damage, the runways are constructed in such a way that they are tethered to the seabed and the concourse will be placed in the center of the estuary.
The access is provided through marine rail tunnels which link directly to central London and the European High Speed Rail Networks. If you prefer car, then airport also provides three parking terminals on land.
The estimated cost of the project is $80 billion. As per the design, the flexibility provides unique opportunity for the runways to float and it can be taken away for maintenance if required.
By floating, it can also save the vast damages of land reclamation in the sensitive Thames. As an attempt to avoid key feeding and high and low water migration areas, the airport location is optimized.
These proposals will pave the way for the largest urban expansion project in Europe with the eco-city. The eco-city named Heathrow Gardens will be massive enough to provide additional homes for 300,000 people and employment for over 200,000.
